6. KEY TO INDIVIDUAL PARAMETERS

The USER MENU is accessed by pressing MODE (or via the selection menu by pressing + or - ). Within this menu, again by

pressing MODE, the following values are displayed consecutively.

FR: Display of rotation frequency

Current rotation frequency with electric pump is controlled, in [Hz].

VP: Display of pressure

System pressure measured in [bar] or [psi] depending on measurement system used.

C1: Display of phase current

Phase current of electric pump in [A]

A round flashing symbol may appear under the phase current C1symbol. This signals that the pre-alarm threshold of maximum current

allowed has been exceeded. If the symbol flashes at regular intervals it means that the motor overcurrent protection is being activated

and that it will probably be triggered. In this case it is necessary to check the correct setting of the maximum current of the RC pump,

see paragraph 6.5.1 and the electric pump connections.

PO: Display of the power delivered

Power delivered to the electric pump in [kW].

A round flashing symbol may appear under the measured power PO symbol. This signals that the pre-alarm threshold of maximum

power allowed has been exceeded.

SM: System monitor

Displays the system status in the case of a multi-inverter installation. If there is no communication, an icon is displayed, showing

communication absent or interrupted. If there are several interconnected inverters, an icon is shown for each. The icon bears the

symbol of a pump with pump status indications below.

Depending on operating status, the item in Table 15 is displayed.

Inverter in run

Inverter in standby

Inverter in fault

If the inverter is configured as reserve, the upper section of the icon representing the motor is displayed in colour, while the display

remains the same as in Table 15 with the exception that if the motor is stationary F is displayed instead of Sb.

If one or more inverters have RC without a setting, the letter A appears in place of the status information (below all icons of the

inverters present), and system start-up is disabled.
